In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.

In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.

Eggs are placed in vinegar for one or two days to dissolve the shells. Then, learners place the eggs in water or corn syrup and observe them over a period of days.

In this activity, learners will build a design and build a place for pollinators to drink from.

In this forensics activity, learners solve a mystery using “DNA” taken from the scene of the crime.

In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

In this botany activity, learners will create an experiment about seed germination. This activity gives students an opportunity to explore how seeds germinate and react to surrounding conditions.

In this math activity, learners collect, organize, and analyze a set of data related to types of animals in the temperate forest.

In this simple activity (on page 2 of the PDF), learners make a crystal garden using salt, water, and a brick.

In this two-part activity, learners compare and contrast a variety of life cycles to better understand different organisms and how they develop.
